White Castle Hamburger Recipe

Ground beef: The main protein for the sliders, providing a rich and savory base.

Dry onion soup mix: Adds a burst of onion flavor and seasoning to the beef.

Water: Helps to mix and distribute the soup mix evenly throughout the beef.

American cheese: Melts perfectly over the beef, adding a creamy texture and flavor.

Slider buns: Smaller than regular buns, perfect for making mini hamburgers.

Diced onions: Adds a fresh crunch and additional onion flavor to the sliders.

Pickles: Provides a tangy contrast to the savory beef and cheese.

When spreading the ground beef mixture on the baking sheet, use a piece of parchment paper or plastic wrap on top of the meat. This will help you flatten it evenly without sticking to your hands or utensils. Additionally, make sure the diced onions are finely chopped to ensure they cook evenly and blend well with the meat.

• ground beef - Substitute with ground turkey: Ground turkey is a leaner option and can provide a similar texture and flavor when seasoned well.

• dry onion soup mix - Substitute with homemade onion seasoning: Combine dried minced onions, beef bouillon granules, onion powder, and a bit of salt for a similar flavor profile.

• water - Substitute with beef broth: Beef broth adds more depth of flavor compared to plain water.

• american cheese - Substitute with cheddar cheese: Cheddar cheese melts well and provides a rich, creamy texture similar to American cheese.

• slider buns - Substitute with Hawaiian rolls: Hawaiian rolls are slightly sweet and soft, making them a delicious alternative for slider buns.

• diced onions - Substitute with shallots: Shallots have a milder and slightly sweeter flavor, which can complement the other ingredients well.

• pickles - Substitute with cucumber slices: Fresh cucumber slices can add a crisp texture and a mild, refreshing flavor.

• Allow the hamburger patties to cool completely before storing. This prevents condensation, which can make the buns soggy.
• Wrap each slider individually in plastic wrap or aluminum foil. This helps maintain their shape and prevents them from sticking together.
• Place the wrapped sliders in an airtight container or a resealable freezer bag. If using a freezer bag, remove as much air as possible to prevent freezer burn.
• Label the container or bag with the date. This ensures you know how long they've been stored and helps you use them within a safe time frame.
• Store the sliders in the refrigerator for up to 3 days. For longer storage, place them in the freezer where they can last up to 3 months.
• When ready to reheat, unwrap the sliders and place them on a microwave-safe plate. Cover with a damp paper towel to retain moisture.
• Microwave on medium power for 1-2 minutes if refrigerated, or 2-3 minutes if frozen. Alternatively, reheat in a preheated oven at 350°F (175°C) for 10-15 minutes until heated through.
• If you prefer a crispier texture, reheat the sliders in a skillet over medium heat for a few minutes on each side.
• Add fresh pickles and diced onions after reheating to maintain their crunch and flavor.
• Enjoy your White Castle hamburgers just as delicious as when they were first made!

• Preheat your oven to 350°F (175°C). Place the hamburgers on a baking sheet and cover them with aluminum foil to prevent them from drying out. Heat for about 10-15 minutes or until warmed through.

• If you prefer using a microwave, place the hamburgers on a microwave-safe plate. Cover them with a damp paper towel to retain moisture. Microwave on medium power for 1-2 minutes, checking halfway through to ensure they are heating evenly.

• For a quick stovetop method, heat a non-stick skillet over medium heat. Add a small amount of olive oil or butter to the pan. Place the hamburgers in the skillet and cover with a lid. Heat for 2-3 minutes on each side until warmed through.

• If you have an air fryer, preheat it to 350°F (175°C). Place the hamburgers in the air fryer basket in a single layer. Heat for about 3-5 minutes, checking halfway through to ensure they are heating evenly.

• For a toaster oven, preheat to 350°F (175°C). Place the hamburgers on a baking sheet and cover with aluminum foil. Heat for about 10 minutes or until warmed through.

• Mixing bowl: Use this to combine the ground beef, onion soup mix, and water thoroughly.

• Baking sheet: Spread the meat mixture evenly on this surface for baking.

• Spatula: Helpful for spreading and flattening the meat mixture on the baking sheet.

• Oven: Preheat and bake the meat mixture at the specified temperature.

• Knife: Cut the baked meat into small squares to fit the slider buns.

• Cutting board: Use this as a surface to dice the onions and cut the meat squares.

• Measuring cup: Measure out the water and diced onions accurately.

• Serving platter: Arrange the assembled sliders on this for serving.

Prepare ingredients ahead: Dice the onions and mix the ground beef with the onion soup mix the night before.

Use parchment paper: Line your baking sheet with parchment paper for easy cleanup and to prevent sticking.

Pre-cut cheese: Slice the American cheese in advance to save time during assembly.

Batch cooking: Double the recipe and freeze extra sliders for a quick meal later.

Use a rolling pin: Flatten the meat mixture evenly with a rolling pin to ensure uniform cooking.
